kunit: string-stream: Add option to make all lines end with newline

Browse Source 
Add an optional feature to string_stream that will append a newline to
any added string that does not already end with a newline. The purpose
of this is so that string_stream can be used to collect log lines.

This is enabled/disabled by calling string_stream_set_append_newlines().
